preamplifier after preamplifier?


Hi.

I have a preamplifier and a poweramplifier I am very satisfied with.
The preamplifier is connected to the poweramplifier and the powerampfiler is connected to speakers,
The connection between the pre- and power-amplifiler is also spited to two active subwoofers.

However, I miss the option to control my sub-woofers volume relative to the speaker volume.
My pre don't have any settings for tuning this, just volume +/-

Can I connect a Second pre-amp with independent volume before the sub-woofers? will this cause any damage or problems?
It might be easier to understand this drawing:


Pre #1: pro-ject pre box s2 digital
Pre #2: AIYIMA Tube Pre

You could bet a Parasound P7 which has this built in. So does the 5 and 6. 

*L*  I was going to hawk the 2496 active xover, but the old heavy was light on his feat.... *s*  Won't cost like another pre, either....

@fuzztone  and lighter on the entry fee, too....and I'm amazed at the 'one remote to bind us' approach.

( *note to self*  Do Not 'Thumb Fight' with this man. )

The one thing I really like with a DCX2496 is I can run Behringer amps with it and they are made for each other. I use up to 3 NU12,000. All the drivers are direct coupled, no crossovers between the power amps and subs.

About 2000 watts @ 8 ohms 4000 @ 4 ohms. I’ve pushed 1 ohm for a while, 2 ohms no problem at all. They have very good cone control, the best I’ve ever seen actually, other than servo.. At 8 ohms. Clear deep solid bass. Those 12K will pump it out. They were about 500.00 each. They are close to 800.00 or more now. The secret is out. :-) I can’t break one. I been trying for over 6 years now..

Using my Marchand crossover and passive subs, I set the gain on the crossover @ 10am and the mains at 3pm.  Quite a difference.  And I have very efficient speakers. May not help here but it is possible to use high efficiency speakers.
